Principal Kathy Ritter confirmed that 12 male and six female students entered the building after hours. They brought with them an estimated 2,000 uninflated balloons and an undetermined number of pennies.

“I think they were trying to a do a fairly innocent prank,” Ritter said.

The students will not be kept from participating in any senior activities, including graduation. However, they might face charges from the police department, Ritter said.

Police files indicate that the students were all arrested on suspicion of trespassing.

Public Information Officer Jessie Haden has yet to return phone calls to confirm charges the students will face.
